Interview a few different solar panel installers before choosing the one for you. You've made a big investment by choosing solar panels, and you don't want any costly mistakes occurring during the installation. Find a team that knows their stuff. A company that has a track record that you can respect.
Is it worth getting solar panels installed on your property?
Cleaning your solar panels does not need to be labor intensive. You want to avoid abrasive soaps at all costs, as they can deteriorate and even destroy your panels. So long as there is not caked up dust or bird droppings, frequent rinses with just hose water should be more than enough.
